The error message doesn't have to do with the fan control signal.
The error is that the model cannot determine the energy transfer
coefficients for the tower given the parameters that you have
entered. For example, if you give a design outlet fluid temperature
that is below the design wet bulb temperature then it is physically
impossible for a tower to deliver such an outlet water temperature
and the model will generate the error that you received. The fan
control signal appears involved because the energy transfer
coefficients are only calculated if the tower is actually on and
running.<br>

<pre wrap="">Dear all,
I'm currently working on a project using a chiller and type 510 cooling tower. The project is given error when the fan control signal is set at 1 at the input tab. What do you think is the cause of this error? Schematics and error message of the project attached.Thank you.
Regards,
Idris
